How we review

Broad accessThe tool can change data, run commands or handle secrets.

  • Can publish and update games on behalf of the developer account
  • The Session_id and CSRF token grant full console access rather than scoped rights
  • Authentication relies on unofficial cookie access rather than a platform-issued key

This is third-party code. Review the repository files before installing.

What it does

The server offers two tool layers. Public tools need no authentication: searching games by keyword, listing popular games filtered by category, and listing 27 genres, all read from the yandex.ru/games catalog page. Authenticated tools work through the developer console: creating and updating a game draft, uploading a ZIP build as a new version, submitting for moderation, publishing a game that passed review, and checking status or listing every game on the account. Authentication is not an official API key but a Session_id cookie and an X-CSRF-Token header, copied manually from browser DevTools after logging into the console.

Who it is for. For HTML5 game developers who publish to the Yandex Games catalog and want to automate build uploads.

Good fit when

  • You want to quickly browse the catalog, popular games or genre list without logging in
  • You want to automate uploading a new build and submitting it for moderation from a conversation with an agent
  • You run several games on one developer account and need a unified status view

Not a fit when

  • You do not want to manually pull the Session_id and CSRF token from DevTools and store them in environment variables
  • You need an official API instead of unofficial console-cookie access: the project offers no other way

Example request

Check the moderation status of all my games on Yandex Games

MCP

Transport
stdio
Authentication
key is optional

Environment variables

YAGAMES_SESSION_COOKIE secret
The Session_id cookie value from the developer console, needed for game management
YAGAMES_CSRF_TOKEN secret
The X-CSRF-Token header value from the developer console

Limitations

Publishing and build uploads work through unofficial developer-console cookie access rather than a documented API key. The Session_id and CSRF token grant full access to the developer account and have no built-in expiry handling in the project; the author explicitly warns not to share them. Public search is built on parsing the catalog page's HTML and can break if it changes.

How to disable. Remove the server from your MCP client config and log out of the Yandex Games console to invalidate the Session_id.

FAQ

Does game search need authentication?

No, the yagames-search, yagames-popular and yagames-categories tools are public and need no keys or cookies.

Where do I get the Session_id and CSRF token?

From browser DevTools after logging into games.yandex.ru/console: the Session_id cookie under the Application tab, and the X-CSRF-Token header on a POST request to /console/api/application under the Network tab.

README in short

The English README splits tools into public, no-auth ones and authenticated console ones. It gives a tool table, instructions for pulling the Session_id and CSRF token from DevTools with an explicit warning not to share or commit them, config examples for opencode and Claude Desktop, an architecture diagram separating the catalog client from the console client, a list of console REST endpoints, and background on the Yandex Games platform: over 2,000 games, 27 genre categories, ad-based monetization.
